MINING-TOOL.

SPECIFICATION forming part of Letters Patent No. 333,472, dated December29, 1885.

Application filed April 12!, 1885. Serial No. 162,099. (No model.)

To all whom it may concern.-

Be it known that I, JOHN J. LLOYD, a citizen of the United States,residing at Streator, in the county of La Salle and State of Illinois,have invented certain new and useful Improvements in Mining-Tools; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Figure 1 is a perspective view of my improved miningtool. Fig. 2 is alongitudinal vertical sectional View of the same. Fig. 3 is alongitudinal sectional view taken on the line at x in Fig. 2.

The same letters refer to the same parts in all the figures.

This invention relates to mining-tools; and it has for its object toprovide a single or common handle with a large number of bits, such aspicks, drills, axes, and other tools which are constantly required byminers.

The invention consists in the improved construction of the handle andthe bits, which will be hereinafter fully described, and particularlypointed out in the claim.

In the drawings hereto annexed, A designates a suitable handle, thefront end oi'which has a flattened tapering enlargement, B, over which,from the butt-end of the handle, is slipped a correspondiugly-shapedcollar, 0, which is to be made of malleable iron or brass, or othersuitable material.

I) is the tool-head, which is made of cast or wrought metal, and whichis provided with an eye, E, fitting over the flattened head and collarof the handle, and having perforated wings F F, through which and thecollar 0 may be driven a nail, G, or other suitable fastening. The endsof the tool-head are pro- 40 vided with sockets H H, to receive theshanks of the tools or bits which are to be attached thereto. At H hasbeen shown a square socket corresponding with the shape of the bit-shankI, which is retained in position by means of a laterally-insertedset-screw. At H a round socket has been shown, corresponding with therounded bit-shank I, which may be screwthreaded, if desired, and whichmay also, when inserted, be retained by a lateral setscrew.

The bits employed in connection with this invention may be fashionedinto any desired shape or shapes-such as picks, drills, axes, and thelike-and my present invention is not confined to any particularconstruction of the said bits. I would also have it understood that theconstruction of the shanks and sockets by which connection is made withthe head may be changed or modified without departing from the spirit ofmy invention.

Having thus described my invention, Iclaim and desire to secure byLetters Patent of the United States- 7 In a mining tool or drill, thecombination, with a handle having an enlarged flattened tapering end, ofa separate metallic collar or sleeve surrounding a portion of saidflattened end, and a tool-head provided with wings extending over saidsleeve and secured to the handle, substantially as shown and described.

In testimony whereofI affix my signature in presence of two witnesses.

JOHN J. LLOYD.
